You left out an option:

"Nothing. No savings to speak of, but self-funding through my salary at a $DAYJOB or consulting."

That's pretty much where we are at Fogbeam Labs. The plus side is, we have a nearly infinite amount of runway, as long as the co-founders have jobs. The downside is, we're stuck working the $DAYJOBS 40 hours as week, and have to make time for the startup by night + weekend.
